I. On the Initial Space Charge Distribution in a Cylindrical Magnetron Diode

Abstract

Numerical calculations are given for the space charge distribution in a cylindrical magnetron diode, which allow for the thermal emission velocities but neglect electron–electron interaction. In all cases the distribution is of double stream type even when the ratio of the radius of the space charge cloud to the cathode radius is less than two. However, the results obtained are not in agreement with experimental data, described in the companion paper, and a brief outline is given of the lines on which a correct theory might be set up.
